KEY IS ON NEXT PAGE Worksheet on Limiting Reactants Use the following equation to answer questions 1-4. N2 + H2  NH3 1. How many moles of NH3 can be produced from the reaction of 28 g of N2 ? 2. How many moles of NH3 can be produced from the reaction of 25 g of H2? 3. If 28 g of N2 and 25 g of H2 are reacted together, which one would be the limiting reactant? Use the following to answer questions 5-8. C3H8 + O2  H2O + CO2 5. How many moles of water can be produced from the reaction of 28 g of C3H8 ? 6. How many moles of water can be produced from the reaction of 45 g of O2? 7. If 28 g of C3H8 and 45 g of O2 are reacted together, which one would be the limiting reactant? . Worksheet on Limiting Reactants Use the following equation to answer questions 1-4. N2 + 3 H2  2 NH3 1. How many moles of NH3 can be produced from the reaction of 28 g of N2 ? 28 g N2 X 1 mole N2 X 2 moles NH3 = 2 moles NH3 28 g N2 1 mole N2 2. How many moles of NH3 can be produced from the reaction of 25 g of H2? 25 g H2 X 1 mole H2 2 g H2 X 2 moles NH3 = 8.3 moles NH3 3 moles H2 3. If 28 g of N2 and 25 g of H2 are reacted together, which one would be the limiting reactant? N2 would be the limiting reactant because it only makes 2 moles of NH3 before it is used up. Use the following to answer questions 5-8. C3H8 + 5 O2  4 H2O + 3 CO2 5. How many moles of water can be produced from the reaction of 28 g of C3H8 ? 28 g C3H8 X 1 mole C3H8 X 4 moles H2O = 2.55 moles H2O 44 g C3H8 1 moles C3H8 6. How many moles of water can be produced from the reaction of 45 g of O2? 45 g O2 X 1 mole O2 X 4 moles H2O = 1.125 moles H2O 32 g O2 5 moles O2 8. If 28 g of C3H8 and 45 g of O2 are reacted together, which one would be the limiting reactant? O2 would be the limiting reactant because it only makes 1.125 moles of H2O before it is used up.
